The city of Mystras (or Mistras) in southern Greece was the provincial capital of the Byzantine Despotate of the Morea from the 13th through the 15th centuries CE. It was founded in 1249 CE by William II of Villehardouin, and it served as a center of intellectualism in the late Byzantine world. After the fall of the Byzantine Empire, the city surrendered to the Ottomans in 1460 CE and remained in Ottoman hands, with brief interruptions, until 19th century CE. The city was abandoned in 1832 CE, but its spectacular Byzantine ruins continue to attract visitors and are listed as a UNESCO World Heritage Site.
